Attachment 4 - Photos.pdf

This document consists of photographs of industrial mechanical systems and equipment installations. The images depict various components of what appears to be a water treatment or HVAC system infrastructure, including:

Plumbing assemblies with labeled shut-off valves (marked with yellow and blue identification bands), copper and PVC piping networks, and multiple isolation ball valves arranged on manifold racks. Water filtration equipment including an NXT brand multi-stage filter system mounted on blue support frames. Control and monitoring systems featuring RAMIC brand electrical panels with multiple disconnect switches and digital displays. Pump systems including Bison brand equipment mounted on green base platforms and Fluid Energy branded air compressors with associated tank and motor assemblies. Additional mechanical components including pressure relief systems, expansion tanks, and various connecting conduits with insulation wrapping. The installations show professional industrial setup with organized routing of supply and return lines, proper valve isolation points, and integrated electrical control systems typical of commercial building mechanical systems.

The photographs appear to be documentation of installed equipment but do not contain specifications, procurement requirements, performance standards, or other contract-related information necessary for federal contracting purposes. No request for proposal, statement of work, pricing information, or response requirements are present in this document.
